It works with a wide range of solar, battery-powered, and low-voltage lighting systems.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the 30-second sensing delay for?\u003c\/h4\u003e\n\u003cp\u003eA: The built-in 30-second default delay prevents the switch from falsely triggering due to brief, temporary changes in light — such as passing car headlights or a momentary shadow. This ensures stable, reliable automatic operation.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this switch for both day-on and night-on modes?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! This sensor switch features two selectable modes: Night Mode (lights ON when dark, OFF during the day) and Day Mode (lights ON during the day, OFF at night). Simply configure it for your preferred automation needs.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum load current I should use at 24V?\u003c\/h4\u003e\n\u003cp\u003eA: While the switch is rated for up to 5A total, it is recommended to keep the load below 2A when operating at 24V, and below 4A at 12V, to ensure safe and reliable long-term performance.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What voltage systems is this photocell light sensor switch compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This light sensor switch is compatible with DC systems ranging from 3.7V to 24V, including common 5V, 12V, and 24V setups.
